GM faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.

GM To Offer Car That Will Almost Drive Itself

Cars that can talk to each other and almost drive themselves at freeway speeds are just two years away from the showroom, according to General Motors executives. The company announced Sunday that the semi-autonomous system for freeways will be an option on an unidentified new 2017 Cadillac that goes on sale in the summer of 2016. In addition, another 2017 Cadillac, the CTS, will be equipped with radio transmitters and receivers that will let it communicate with other cars, sharing data such as location, speed and whether the driver is applying the brakes. The announcements were made Sunday at the opening of the Intelligent Transportation Society World Congress being held in Detroit this week. They are part of a barrage of similar declarations that are expected from other companies throughout the week as the industry shows off progress toward self-driving and safer cars. The freeway system, dubbed "Super Cruise," uses cameras and radar to keep the car in the center of a lane and also stay a safe distance behind cars in front of it. The system will bring the car to a complete stop if traffic halts without driver action, and it can keep the car going in stop-and-go traffic. Other automakers, such as Mercedes-Benz, now offer similar systems that work at low speeds, but GM says it's the first to announce a system that operates at highway speeds. Others could have freeway systems in two years, though. "If the mood strikes you on the high-speed road from Barstow, California, to Las Vegas, you can take a break from the wheel and pedals and let the car do the work," CEO Mary Barra said in remarks prepared for the conference's keynote address on Sunday. But GM said the car still won't drive itself, and the company is working on a system to monitor drivers to make sure they're still paying attention. Details of that system weren't released. "Sensing technology is not yet to the point where the driver can check out," said John Capp, GM's director of global safety strategy. "This is a level of automation that can be done, that is feasible." The new Cadillac that will get Super Cruise hasn't been officially announced yet. But executives have hinted that GM will build a big rear-drive Caddy to lead its lineup in the coming years. Also Sunday, the Michigan Department of Transportation announced that it will partner with GM, Ford Motor Co.

Cadillac recalls ELR coupe over stability control problems

Cadillac is recalling about 656 2014 ELR models made between September 26, 2013 and February 14, 2014, because of a fault with the electronic stability control system. On cars without adaptive cruise control, it's possible that diagnostics could prevent the system from telling the driver if ESC is on or off.
Cadillac has a software fix ready and repairs begin on April 17. Alan Adler, General Motors' recall and legal spokesperson, tells Autoblog that only about 55 of the affected cars are in the hands of owners. The rest are either on dealer lots or still at the factory. There have been no reported injuries or crashes caused by the fault.
The correction for the stability control system involves a software recalibration of the electronic brake control module that takes around 20 minutes to perform. While they use the same platform, the Chevrolet Volt isn't involved in this recall because it "uses a different a brake control module," said Adler.
